Claim of US Patent No. 10,172,220

1. A pairing method in an illumination system including: a plurality of luminaires; a plurality of access devices; and an illumination controller that communicates with the plurality of access devices,the pairing method comprising:
broadcasting, by each of the plurality of access devices, a first command signal to parts of the plurality of luminaires, the first command signal commanding each of the parts of the plurality of luminaires that receive the first command signal to transmit information regarding the each of the parts of the plurality of luminaires as a reply;
receiving, by each of the plurality of luminaires, one or more command signals including the first command signals broadcasted from one or more access devices;
after receiving the first command signal, transmitting, by each of the plurality of luminaires, first information as the reply to one or more access devices among the plurality of access devices, each of which has broadcasted the first command signal, the first information including identification information of the each of the plurality of luminaires and a radio field intensity of the first command signal received by the each of the plurality of luminaires;
after receiving a plurality of pieces of the first information, transmitting, by each of the plurality of access devices, second information to the illumination controller, the second information including identification information of each of the plurality of access devices and the plurality of pieces of the first information received by the each of the plurality of access devices; and
after receiving a plurality of pieces of the second information, pairing, by the illumination controller, based on the plurality of pieces of the second information, each of the plurality of luminaires and one of the plurality of access devices, wherein:
in the pairing, the illumination controller determines whether a given luminaire to be paired has transmitted the first information to only one access device or to two or more access devices, among the plurality of access devices,
when it is determined that the given luminaire to be paired has transmitted the first information to only one access device included in the plurality of access devices, the illumination controller determines to pair the given luminaire and the one access device, and
when it is determined that the given luminaire to be paired has transmitted the first information to the two or more access devices included in the plurality of access devices, the illumination controller determines to pair the given luminaire and one access device included in the two or more access devices which has a highest radio field intensity.
